Help deciding on new AMP and possibly a DAC.

Hi all. I really need advice here, don't want to make a purchase Ill regret and I really would appreciate any advice or suggestions you could put forward.

Ideally I want to sell my Asus Xonar STX to free up funds to buy a desktop amp. I had considered Magni/Modi, but Im intrigued by Valhalla. Problem is, if i sell my STX then im left with only onboard mainboard sound, so Im guessing I would be better off with a Magni/Modi combination purely for the DAC. I listen to music through my computer only. I could happily spend £270 for Modi and Valhalla but would prefer to reserve funds so I can fund purchase of another pair of IEM's. Does Valhalla warrant the extra above the Magni?
